Cassidy says he first noticed symptoms two-and-a-half years ago, leading him to visit the doctor. "When friends or family members ask you, ‘Remember, I just told you this two days ago?’ and there’s no memory of it … that’s when I began to be very concerned,” Cassidy says of the first symptom he noticed.

The former teen heartthrob, who shot to super-stardom in 1970 as Keith Partridge on the hit TV series The Partridge Family, addresses accusations that he was intoxicated at his last concert performance and discusses the status of his current relationship with his family and his fear of being a burden to them.

“I want you to promise me you’ll find a way to let me go and don’t let me live like that,’” Cassidy says he told his son about not wanting to succumb to the disease as his mother did.

And, Cassidy, who says that the brain disease has forced him to retire and stop performing after a half century, opens up about his past alcoholism and whether he believes it contributed to his condition.
